vue sso 单点登录

sso单点登录有很多种实现方式，我这只是采用一种最简单的实现方式
vue2 + 采用mock.js来模拟后台接口验证

实现的思路
sso-serve 一个独立的登录系统 http://localhost:8090/
sso_client 子级系统，所有子系统的逻辑大概相同

子系统通过截取浏览器的url 地址来判断当前系统是否登录
如果未登录则跳转到sso登录界面并会带上当前系统的url地址
sso登录界面验证账号密码，通过后会根据之前带过来的子系统url地址跳转，并带回参数st，st=后面的值在子系统在调用后台接口去验证，验证通过则会在浏览器set一个Cookies,后面打开子系统的话会根据这个Cookies来验证登录状态

sso界面获取当前的url地址做逻辑判断
sso 登录页代码
